Abstract (en)
The present invention relates to a multi-layer X-ray detector (10), comprising: a first X-ray converter (20); a first sensor (30); a second X-ray converter (40); a second sensor (50); and an internal anti-scatter device (60). The first X-ray converter is located at a first X-ray conversion layer. The first sensor is located at a first sensor layer. The second X-ray converter is located at a second X-ray conversion layer. The second sensor is located at a second sensor layer. The first X-ray converter and the first sensor form a first detector pair, wherein the first sensor is configured to detect radiation emitted from the first X-ray converter generated from the conversion of X-rays in the first X-ray converter. The second X-ray converter and the second sensor form a second detector pair, wherein the second sensor is configured to detect radiation emitted from the second X-ray converter generated from the conversion of X-rays in the second X-ray converter. The internal anti-scatter device comprises a plurality of X-ray absorbing septa walls. The internal anti-scatter device is located between the first detector pair and the second detector pair. No structure of the internal anti-scatter device is located within either layer of the first detector pair and no structure of the anti-scatter device is located within either layer of the second detector pair.
